Abstract
The utility model relates to a relay protection data converter. The relay protection data converter comprises a 232 level converting circuit; the signal end of the 232 level converting circuit is connected with the signal end of a 485 circuit and is connected with a 232 interface; the signal end of the 485 circuit is connected with a 485 interface; and an IRIG-B (Inter-range Instrumentation Group-B) code signal output end of the 232 interface and an input end of the 485 interface are connected with the signal input end of an anti-interfering lightning protection circuit. The data input and the data output are controlled through the 485 circuit; and an IRIG-B code transmits information to a RS-485 (Recommend Standard-485) through a lightning protection filtering loop, so that +5V power supply is guided to an optical data converter RS-232 (Recommend Standard-232), and provides power supply for the optical data converter RS-232. Data conversion is directly performed for a photoelectric converter of an EIA-232 (Electronic Industries Association-232) serial port, and the transmission of time information by the IRIG-B code of a relay protection device can also be realized.
Description
Technical field
The utility model relates to data information transfer, the conversion equipment between relay protection of power system equipment and the information management system equipment, relates in particular to a kind of relaying protection data converter.
Background technology
The relay protection information management system provides unified analysis platform to relaying protection and automatic safety device; Help grasping rapidly the action behavior of electrical network actual state and relaying protection, in time analyze power grid accident, make accurate judgment rapidly and quick recovery system; Simultaneously; Help to grasp the relay protection device situation, analyze the relaying protection action behavior effectively, improve management and operation and maintenance level.Realize that above-mentioned functions needs relay protection device and information management system to carry out exchanges data.In information exchanging process, can use a large amount of RS232/RS485 data converters.At present; Though the RS232/RS485 data converter has finished product on the market, can realize the data transaction of common EIA-232 serial ports, can't be directly the optical-electrical converter of EIA-232 serial ports be carried out data transaction; The IRIG-B sign indicating number that also can't realize protective relaying device to the time transmission of Information; This just need lay data cable again or optical cable transmits this information, causes a large amount of wastes, the complicacy that the loop also becomes.
Summary of the invention
In order to address the above problem; The utility model provide a kind of simple in structure, promptly kept the legacy data converter function; Again can be directly the optical-electrical converter of EIA-232 serial ports be carried out data transaction, the IRIG-B sign indicating number that also can realize protective relaying device to the time transmission of Information the relaying protection data converter.
To achieve these goals; The utility model mainly is able to solve through following technical scheme: a kind of relaying protection data converter; Comprise 232 level shifting circuits; The signal input/output end port of 232 level shifting circuits is connected with the signal input/output end port of 485 circuit, and the signal input/output end port of described 232 level shifting circuits is connected with 232 interfaces, and the signal input/output end port of described 485 circuit is connected with 485 interfaces; The IRIG-B coded signal output of described 232 interfaces is connected with the signal input part of anti-interference lightning protection circuit, and the signal input part of anti-interference lightning protection circuit is connected with 485 interfaces.
The input and output that the utility model comes control data through 485 circuit, the transmission of IRIG-B sign indicating number is delivered to RS-485 through the lightning protection filter circuit with information, and general+5V power supply causes optical data converter RS-232, for it provides power supply.Realized directly the optical-electrical converter of EIA-232 serial ports is carried out data transaction, the IRIG-B sign indicating number that also can realize protective relaying device to the time transmission of Information.
